CONTROLLING APPARATUS FOR AIB-PRESSURE SYSTEMS FOR PUMPS.

Application filed Gotober 29, 1921.

To all whom t may concern.'

Be it known that I, Aueusr F. .l-Linnronr, a citizen of the United States, residing at Tinley Park, in the county of Cook and State of illinois, have invented certain new and useful Improvements in a Controlling Apparatus for Air-Pressure Systems for Pumps, oi which the following is a specification.

l0 This invention relates to new and useful improvements in an air pressure pumping apparatus, which, while it is more particularly intended for use in pumping water Yfrom earth wells and cisterns, yet it is applicable Afor use in pumping water or liquids from various kinds ot containers, whether located above ground or below the same, and has for its principal object to provide a pneumatically operated pumping apparatus 2O which shall be automatic and efficient in its thereof as will be hereinafter more lully set forth and ,specically claimed.

In the accompanying drawings, which serve to illustrate an embodiment oi the involition- Fig. 1 is a general or diagrammatic view oit the apparatus showing it installed in connection with an earth well, with its parts in their operative positions for forcing or pumping water from the well.

Fig. 2 is an enlarged view partly `in section and partly in elevation taken on line 2 2 of Fig. 3, looking in the direction indicated by the arrows, showing certain parts of the apparatus mounted on a suitable support therefor, and in the positions illustrated in Fig. 1.

Fig. 3 is a view of like parts in similar positions looking in' the direction of the pressure controlling,Y cylinder mounted on said support.

Fig. 4f is a similar view to Fig. 2 but showing by continuous lines about the positions the parts will occupy when air pressure is shut off from the source of supply and is being exhausted from the submerged air tank in the welll Serial No. 511,1106.

Fig. 5 is an enlarged view of a portion of the supporting frame of the apparatus and the valve casing for the valves of the supply pipe and exhaust outlet.

F ig. 6 is an enlarged vertical sectional view taken on line 6 6 oit' Fig. e of a needle valve and its casing carried by the pressure controlling cylinder, and

Fig. 7 is a sectional view of a portion of the air tank or vessel located within the well and apart of theair outlet pipe leading from said tank showing the means for supporting a float in said tank and for guiding` a needle valve carried by said float for cooperation with the said air outlet pipe. Said view is taken on line 7 7 of Fig. l.

Corresponding numerals of reference refer to like parts throughout the different views of the drawings.

Referring now more particularly to Fig. 1 ot the drawings, the reference numeral 10 designates a water or liquid container such as a well, in which is suspended so as to preferably be entirely submerged in the water 11 of said container, a tank 12 which is provided in its bottom with a port or opening 13 having around the same on the upper surface of said bottom a valve seat 141 to co-act with a gravity valve 15 for the purpose ot admitting water to said tank. The valve 15 is surrounded by a perforated cage 16 to .prevent the accidental dislocation of said valve and to avoid its being interfered with by a float 17 which is located in the tank lfor the purpose to be presently eX- plained. Located near the well or container is a large tank or vat 18 containing compressed air, which may be supplied thereto by any suitable means, for use for a considerable length of time. Leading from this vat 18 is a pipe 19 which is equipped with a pressure reducing valve 20 of the ordinary` or any well known construction and communicates with a valve casing 21 which forms-a part of a larger valve casing 22 which latter casing is mounted on a suitable `upright support 23 located near the well or liquid container 10 and supported in any .suitable manner. `The valve casing 21 has a port 23a leading to the casing 22', which port is surrounded by an upwardly extended valve seat-24 for co-operation with a valve 25 the stem 26 of whichis vertically mounted on a bar 27 hinged or loosely connected at one` of its ends for vertical movement to a screw 27@ or other suitable pro-X jection depending from the upper surface ot the valve casing 22 near one end thereof. The valve casing` 22 is provided on its upper surface near its end opposite the inember 27'EL with an exhaust valve casing` 28 which is provided with exhaust ports 29 and has vertically and slidably mounted therein a valve stem 30 which carries on its lower end a valve 3l to close the valve seat 32 orn the casing 28.

Depending` trom the valve 3l is an tension 33 which is reduced towards lower end and provided on said end with a head or enlargement 34. The bar 2T which carries the valve stem 26 is provided with an open ended slot 35 at its tree end AIlor loose engagement with the reduced portion of the extension 33 0f the exhaust valve. The upper end ot the valve stem 30 is provided with a head 36 and justbelow the stem with an enlargement or projection 37 between which head and enlargement is located one end of a lever 38 which is i'ulcrumed on the lower portion of the support 23 and is adapted to operate in a slot 39 in said support. That end ot the lever 38 interposed between the head 36 and enlargement 37 o1t` the valve stem 30 is provided with an open ended slot 40 tor the reception and operation of said valve stem.

Leading from the end ot the valve casing 22 opposite the support 23 is a pipe4l which is extended through the cover 42 ot the well or water container l() and communicates at its lower end with the upper end of the tank l2 to which end ot said tank it is secured in such a manner as to assist in supporting the same. This last mentioned pipe is employed for conveying compressed air from the valve casing 22 to the tank l2 and may be fixed to thecover 42 of the water container in any suitable manner so as to assist in sup portino; the said tank. The upper portion of the support 23 is deflected as shown and has mounted on its upper end a bracket 43 in which is liournaled a pulley 44 over which is extended a cable or cord 45 which supports at its lower end a rod 46 which has mounted thereon a weight 47 and which rod extends into a vertically disposed guide 48 mounted on a bracket 49 with which the"support 2 3 is provided at a suitable distance above its lower end.

Slidably mounted on the lower end of the rod 46 is another weight 50 which is adapted l:

its

vlor vertical movement in the guide 48 and in order to restrict its movement in one direction with respect to the rod 46, said rod is provided with an enlargement 51 on its lower end to engage the weight when said rod is in its low-ermost position, as shown in Figs. 1 t0 Srinclusive oit' the drawings. The `cable or cord 45Ais exten ded over another pulley 52 journaled on a bracket 53 supported on the upper portion of the support at a suitable point thereon. The crosspieces and 56 are disposed in parallelism with one another' in such a manner that their path ot travel will diametrically intersect the cylinder 5T in the operation ot the apparatus.

Extended it'roin the upper end oi the c vlinder 5T is a pipe 58 which extends through the cover 42 ot the well or water container as well as to the top of the tank l2 to which top it is connected b v means ot a valve casing` 59 in such a way as to assist in supporting` said tank, it being-understood that the pipe 58 is suitably iixed to the cover' ot the well through which it is extended. rlhe valve casing` 59 is provided with ports 60 and 6l with which a needle valve 62 co-operates to open and close the same. This needle valve7 as is clearly shown in Figs. l and 7 of the drawings, constitutes a part of the supportina' rod 63 1for the float l?, which Vfloat is iixed on the lower portion oi said rod to 'the end., that in the movement of the iioat, the valve 62 which ex ends into a suitable opening in the valve casing` 59, will be actuated so as to open and close the port 607 therebyshutting` ott or permitting flow of air from the tank l2 to and through the pipe 58 to the upper end of the pressure controlling` cylinder.

The pipe 58 is provided near said cylinder with a check valve 64 ot anvwell known type. Extended through the cover of the well or water container Vi0 is a water service pipe 65 which may be equipped with a branch pipe 66 and a faucet 67 for drawing water from the tank l2. into which the pipe 654 is extended to a point near the bottoni of said tank. This pipe 65 is also so connected to the cover 42 and the top ot the tank l2 as to assist in supporting' said tank. Fixed on Ythe pipe 65 at a suitable point above the float 17 is one end oit an arm 68 the other end et which is provided with a sleeve 69 through which the rod 63 of the float is extended tor vertical movement. This rod is provided just above the upper end of the sleeve 69 with a projection TO to contact with the sleeve 69 so as to restrict the downward movement ot the rod and the float which it carries. but so as to permit sufficient movement of said rod to allow air from the tank l2 to pass 'through the ports 60 and 61 into the pipe 58 and from thence into the pressure controlling cvlinder.

The upper end ot the cvlinder 57 has mounted thereon a valve casing 7l which is Leases@ provided with a valve seat 72 for the needle valve 7? and with ports 74 and 75, the latter ot which leads from the valve seat into said cylinderl The valve T3 is adjustably mounted in the casing 7l so as to regulate the quantity of air which passes :trom or into the cylinder. Located in the cylinder for reciprocatory movement is a piston head 76 the piston rod 77 of which extends through the bottom of the piston and is connected at its lower end to the cross-piece 56 midway between the connections which unite said piece to the cross-piece 54 which located and operates above the upper end of the cylinder. By this arranfement it is manifest that the piston rod 'i7 will be vertically guided in its movements so that there will be no lateral movement thereot.

Fulcrumed on one side ot the bracket 49 which supports the guide 48 for the weight 50 is a gravity actuated bell-crank-lever 78, the longer arm of which is provided with an outward extension 7 9 having an open ended slot tor the reception and operation of the piston rod 77. The shorter arm 80 ot the lever 7 S is provided with a hook 8l which is adapted. when the lever is moved by its gravity to the position shown in Fig. 4 ot' the drawings, to pass through a slot 82 in the guide 48 and engage a notch or opening 83 in the side ot the weight 50 adjacent said lever so as to hold the weight 50 in its raised position. rlhe upper end of the service pipe has preferably mounted thereon an expansion chamber S4 for the purpose of retaining a reserve supply ot water. The longer of the lever 78 is extended through a vertical slot 85 in the support 23 may receive the piston rod ot the cylinder.

From the foregoing` and by reference to the drawings it will be readily understood and clearly seen that. assuming the parts to be in the positions shown in Figs. l to 3 inclusive ot the drawings.` compressed air ifrom the vat or reservoir 18 will pass through the pipe 19 and pressure reducing valve 2() which valve may be so adjusted as to permit a predetermined pressure of air to pass through the pipe 19 to the valve casing 2l and Lfrom thence through the valve casing 22 and pipe 4l to the submerged tank or receptacle 12lo cated as be'tore stated, within the well or water Container and at any suitable distance below the water level thereof'. As the tank l2 is only partially iilled with water, it is apparent that the space therein above the water will be filled with air. the degree of pressure of which will be regulated by the reducing valve 20 above mentioned. rlhis pressure within the tank l2 against the water in said tank is considerably greater 'than the atmospheric pressure on the main body of water in the well and consequently will 'torce the water through the pipe 65 so as to be drawn ott through the faucet 67 when the same is opened, and when it is closed, into the expansion tank 84 for a reserve supply. its soon as a sutlicient quantity ot water within the tank l2 is exhausted therefrom through the pipe 65 to permit the float l? to be lowered, it is obvious that the needle valve 62 on the upper end of the iioat supporting rod 63 will be withdrawn 'from its seat suiiiciently to let air escape through the ports 60 and 6l and thence through the pipe 5S to the upper end of the cylinder 57 and against the piston head 76 in said cylinder. This pressure being greater than the combined resist ance created by the weights 47 and 50, will cause the piston and its rod to be quickly lowered to about the position shown in Fig. 4, in which movement the cross-piece 56 on the lower end ot the piston rod 77 will strike the head 36 oi: the exhaust valve stem 30 and thus depress the bar 27 with which the exhaust valve 3l co-operates and thereby cause the valve 25 to be seated, (see Fig. and thus shut ofi" the air pressure to the tank 12 through the pipe 4l whieh leads from the valve casing 22 to said tank. rit this instant pressure from the valve casing- 22 will be eX- hausted through the port 29 of the valve casing 28 as is obvious. In the above mentioned downward movement ot the piston and its rod, the crosspiece 56 will be disengaged from the extension 79 of the trip lever 7 8, thereby permitting said lever to assume about the position shown by dotted lines in Fig. 2, so that in the upward movement of the weight 50, which will occur during said downward. movement of the piston rod. its rounded head will strike the hook 81 and cause the shorter arm and hook ot said lever to be moved outwardly ot the guide 48 to such a position alongside the weight 50, that the hook will automatically engage the notch or opening 83 in said weight, when the latter is su'tliciently elevated,A and thus hold it until the said lever is tripped by the upward movement of the piece 56 and piston rod. As the rod 46 is slidably mounted in the weight 50. it is manifest it and its weight 47 will have independent movement with respect to the weight 50. as shown in Fig. 4 by dotted lines.

In order to maintain a reserve supply of water in the expansion tank 84. the water service pipey 65 is provided with a check valve 86 which is b v preference located in the water container l() above the water level thereof.

lJVhile l'. have shown the tank .l2 as being completely submerged in the water of the water container or well` yet l desire it to be understood that the tank l2 may be extended int-o the water to a suitable depth without a iger-eeen being completely submerged thereim and ilior this reason l do not desire 'to he limited to the sulnnerged position ot said tank except Where specitieally so set forth in the claims. Having thus fully described my invention,
